Why should industrial valves be imported? -- Problem Chain and Professional Answers

In industries such as petroleum, chemical engineering, and power, harsh working conditions impose extremely high demands on valves. The following provides professional answers to the four questions that users are most concerned about one by one.

Q1: What are the core advantages of imported industrial valves over domestic ones?

The core advantages of imported industrial valves lie in four aspects: technological accumulation, material processing, reliability and brand verification.

1. Leading core technology: Foreign brands have accumulated profound experience in valve design, material science, and sealing technology, and their performance is particularly stable under extremely harsh working conditions such as high temperature, high pressure, and corrosive media. Take supercritical power stations as an example. Imported industrial valves have more mature solutions.

2. Strict material and process standards: Imported industrial valves often use high-grade alloys, special steels or composite materials, and ensure durability through precise processing. The quality control system (such as API, ASME, and PED certifications) is more stringent, reducing the risk of leakage or failure.

3. Improved safety redundancy design: The safety redundancy design and failure protection mechanism of imported industrial valves are more complete, ensuring higher reliability under special working conditions.

4. Brand Reputation and long-term Verification: With nearly a hundred years of development, its safety and reliability have been verified by global projects, and it has accumulated a deep reputation with high user trust.

W&T was founded in 1932 and has been dedicated to the research and application of industrial valves, with profound technical accumulation. At present, it has transformed into a complete machine production mode of the Russian production base, completing core manufacturing and complete machine assembly in accordance with German technical standards to ensure imported quality.

Q2: What are the advantages of the material and process standards for imported industrial valves?

Answer: Imported industrial valves have stricter standards in material selection and processing techniques, and more complete quality system certifications.

Imported industrial valves often use high-grade alloys, special steels or composite materials, and their durability is ensured through precise processing (such as CNC machine tools and laser welding). The quality control system covers international certifications such as API, ASME, and PED, and implements full-process control from raw material entry to finished product exit, effectively reducing the risk of leakage or failure.

Viti holds a variety of quality control system certification certificates recognized both domestically and internationally. Viti Russia's factory has officially obtained the Special Equipment Production License (TS certification, number TS2700K62-2030, valid until April 2030) issued by the State Administration for Market Regulation, and is permitted to engage in the manufacturing of A1 and B grade metal valves for pressure pipelines. At the same time, it has obtained the Special Equipment Type Test Certificate (TSG certification). The gate valve covers PN≤32.0MPa, DN≤600mm, and temperatures ranging from -20 to +625℃, while the butterfly valve covers PN≤16.0MPa, DN≤1000mm, and temperatures ranging from -20 to +425℃. Both are of the highest grade A1.

In addition, Viti has obtained three international system certifications, namely ISO 9001, ISO 14001, and ISO 45001, as well as multiple qualifications such as CE certification, SIL certification, explosion-proof qualification certificate, ISO 15848 low emission certification, and API 607 fire protection certification.

Q3: How reliable are imported industrial valves under special working conditions?

Answer: Imported industrial valves have more complete safety redundancy designs and failure protection mechanisms under harsh working conditions, making them suitable for use in critical workstations.

In high-end fields such as supercritical power stations, petrochemicals, and coal chemicals, the failure of valves may bring serious safety risks and economic losses. Imported industrial valves, through material selection, structural optimization and multiple sealing designs, maintain stable operation under extreme working conditions such as high temperature and high pressure, strong corrosion and high erosion.

Under the current harsh working conditions in China, Viti maintains a leading position in production industry and technology. Its multi-stage pressure reducing regulating valve adopts a maximum nine-stage pressure reducing design to prevent erosion, flash evaporation and cavitation. The pressure-reducing sleeve adopts a three-stage pressure-reducing design of expansion, collision and offset, which can reduce the pressure by 70% and fundamentally eliminate the destructive force of cavitation. The product has been successfully applied in large-scale projects such as the Jinguo Neng Lingwu 2×1000MW ultra-supercritical heating renovation project (608℃/5.67MPa), Huaneng Tai 'an 2×9F Class Gas Turbine Project, and Huadian Wangting Power Plant's domestic longest distance heating renovation project.

Q4: Imported industrial valves are more expensive. How to balance costs and risks?

Answer: The manufacturing and transportation costs of imported industrial valves are high, and their selling prices are indeed higher than those of domestic valves. When selecting a type, a comprehensive assessment should be made based on the pressure rating, medium characteristics, and life cycle cost.

It is suggested to make rational choices from the following dimensions:

Pressure rating: For high-pressure and ultra-high-pressure working conditions, imported brands are preferred

Medium characteristics: Special attention should be paid to the reliability of sealing for highly corrosive, toxic, flammable and explosive media

Life cycle cost (LCC) : It comprehensively considers the purchase price, maintenance frequency, downtime loss and spare parts supply

Vitai products have directly replaced the original imported brands in many large-scale projects. For instance, the LV valve of Datang Harbin No.1 Thermal Power Plant was replaced with the original brand through direct procurement, which verified its reliability and cost-effectiveness. Vitesse Asia Pacific Center is located in Jinan, Shandong Province. It is fully responsible for business promotion and localization services in the Chinese market and can provide rapid technical support and spare parts supply.

Summary

The core logic for selecting imported industrial valves is: first, clarify the working condition parameters and reliability requirements; then, evaluate the material process and certification qualifications of the imported brand; and finally, make a comprehensive decision based on the life cycle cost.

W&T, based on German technology, supported by Russian complete machine production, and guaranteed by A1-level TS/TSG qualifications, provides reliable imported valve solutions for the harsh industrial conditions.
